+    Extension objects for them.
+
+    :param module_list: As module list, pass either a glob pattern, a list of glob
+                        patterns or a list of Extension objects.  The latter
+                        allows you to configure the extensions separately
+                        through the normal distutils options.
+                        You can also pass Extension objects that have
+                        glob patterns as their sources. Then, cythonize
+                        will resolve the pattern and create a
+                        copy of the Extension for every matching file.
+
+    :param exclude: When passing glob patterns as ``module_list``, you can exclude certain
+                    module names explicitly by passing them into the ``exclude`` option.
+
+    :param nthreads: The number of concurrent builds for parallel compilation
+                     (requires the ``multiprocessing`` module).
+
+    :param aliases: If you want to use compiler directives like ``# distutils: ...`` but
+                    can only know at compile time (when running the ``setup.py``) which values
+                    to use, you can use aliases and pass a dictionary mapping those aliases
+                    to Python strings when calling :func:`cythonize`. As an example, say you
+                    want to use the compiler
+                    directive ``# distutils: include_dirs = ../static_libs/include/``
+                    but this path isn't always fixed and you want to find it when running
+                    the ``setup.py``. You can then do ``# distutils: include_dirs = MY_HEADERS``,
+                    find the value of ``MY_HEADERS`` in the ``setup.py``, put it in a python
+                    variable called ``foo`` as a string, and then call
+                    ``cythonize(..., aliases={'MY_HEADERS': foo})``.
+
+    :param quiet: If True, Cython won't print error, warning, or status messages during the
+                  compilation.
+
+    :param force: Forces the recompilation of the Cython modules, even if the timestamps
+                  don't indicate that a recompilation is necessary.
+
+    :param language: To globally enable C++ mode, you can pass ``language='c++'``. Otherwise, this
+                     will be determined at a per-file level based on compiler directives.  This
+                     affects only modules found based on file names.  Extension instances passed
+                     into :func:`cythonize` will not be changed. It is recommended to rather
+                     use the compiler directive ``# distutils: language = c++`` than this option.
+
+    :param exclude_failures: For a broad 'try to compile' mode that ignores compilation
+                             failures and simply excludes the failed extensions,
+                             pass ``exclude_failures=True``. Note that this only
+                             really makes sense for compiling ``.py`` files which can also
+                             be used without compilation.
+
+    :param show_all_warnings: By default, not all Cython warnings are printed.
+                              Set to true to show all warnings.
+
+    :param annotate: If ``True``, will produce a HTML file for each of the ``.pyx`` or ``.py``
+                     files compiled. The HTML file gives an indication
+                     of how much Python interaction there is in
+                     each of the source code lines, compared to plain C code.
+                     It also allows you to see the C/C++ code
+                     generated for each line of Cython code. This report is invaluable when
+                     optimizing a function for speed,
+                     and for determining when to :ref:`release the GIL <nogil>`:
+                     in general, a ``nogil`` block may contain only "white" code.
+                     See examples in :ref:`determining_where_to_add_types` or
+                     :ref:`primes`.
+
+
+    :param annotate-fullc: If ``True`` will produce a colorized HTML version of
+                           the source which includes entire generated C/C++-code.
+
+
+    :param compiler_directives: Allow to set compiler directives in the ``setup.py`` like this:
+                                ``compiler_directives={'embedsignature': True}``.
+                                See :ref:`compiler-directives`.
+
+    :param depfile: produce depfiles for the sources if True.

+            def f(x):

+            %%cython --compile-args=-fopenmp --link-args=-fopenmp
+            ...
+
+        To enable profile guided optimisation, pass the ``--pgo`` option.
+        Note that the cell itself needs to take care of establishing a suitable

+        optimise, and then calling them directly in the same cell on some realistic

+
+        In Python 3.5 and later, you can distinguish between the profile and

+    r"""Weighted projection of B with a user-specified weight function.
+
+    The bipartite network B is projected on to the specified nodes
+    with weights computed by a user-specified function.  This function
+    must accept as a parameter the neighborhood sets of two nodes and
+    return an integer or a float.
+
+    The nodes retain their attributes and are connected in the resulting graph
+    if they have an edge to a common node in the original graph.
+
+    Parameters
+    ----------
+    B : NetworkX graph
+        The input graph should be bipartite.
+
+    nodes : list or iterable
+        Nodes to project onto (the "bottom" nodes).
+
+    weight_function : function
+        This function must accept as parameters the same input graph
+        that this function, and two nodes; and return an integer or a float.
+        The default function computes the number of shared neighbors.
+
+    Returns
+    -------
+    Graph : NetworkX graph
+       A graph that is the projection onto the given nodes.
